The more probable answer is b: power plant effluent; golf course runoff, although a: <span>power plant effluent; an underground coal mine drain, is also a possible answer.
The source of effluent from a power plant occupies a small, well defined space, i.e. an effluent pipe. This is what is known as a point source, as you can identify with high confidence the spatial and temporal boundaries of the source of pollution. Point sources are relatively easy to quantify and manage because they are so well defined in space and time. Reducing pollution from point sources could be achieved by simply treating effluent to a higher standard or reducing the amount of effluent released. Runoff from land, such as a golf course, is what is defined as a non-point source pollutant. The spatial and temporal aspects of this sort of pollution are much harder to define, as the pathways of runoff from the land into the river may be highly dispersed and variable over time. These sorts of pollution are therefore much harder to quantify and manage.</span>

In deserts, the wind picks up small particles and leave behind larger rocks to form Desert pavement. Moving sand may blast rocks and other features to create ventifacts.The sand is transported until it is deposited in a sand dune.
The human gene mutation database (HGMD) is a collection of published germ-line mutations in nuclear genes that underlie , or are closely associated with human inherited disease.
For identifying the pathogenic mutation among thousands to millions of genomic variant is a major challenges and prioritization strategies are required. Current strategies for Mendelian disease gene identification by exome re-sequencing.
Next generation sequencing (NGS) has been used to identify new pathogenic mutations and genes causing rare genetic diseases. The analyses of NGS data is not trivial and required a technically and biologically rigorous pipeline that address the data quality , accurate variant filtration to minimize mistakes.
